METALLIC Roo-PACKING.

SPECIFICATION forming part of Letters Patent No. 267,750, dated November 21, 1882.

` Application med Aprileisse. (No model.) j

To all whom 'it may concern:

y Beit known that I, LEOPOLD KATZENSTEIN,

'of New York, in the county and State of New York, have invented a new and Improved Metallic Rod-Packing, of which the following is a specilication z This invention relates to an improved metallic packing, which may be used for pistonrods and other similar purposes-as, for example, for packing thejoints ot' steam or other pipes; and the special object ot' this present invention is to` produce a packing which shall be readily and easily put in place, and which, ou account of its elasticity,"will adjust itselt and Iyield when, t'or example, there is some displacement or movement ot' the pipejoints or of'the rod. The packing is also to be ot such construction that steam and water will assist in keeping it right.

The invention consists in makingthe packing-rings hollow, and, by preference, triangular in shape, and alternating around the rod or pipe, so that the hase of one triangular ring and the apex of the next triangular ring will come next to the surface of the pipe or rod to be packed. The rings will thus tit closely one against another, any number of them desired being used.

The invention also consists in making each of these packin g-rin gs of a hollow tube, around which is wound orspun metallic wire, the whole being covered with a fibrous coating of asbestus, or equivalent fibrous strands, wound or spun around the wire to prevent the metallic surfaces ofthe several rings from coming into contact, said construction making this packing flexible, and adaptable to the purposes for which it is intended to be used, all has hereinafter more fully described.

The invention also consists in leaving said hollow rings open at the. ends or other places for the admission of steam or water to their interior. i

In the accompanying drawings, Figure 1 represents a longitudinal sectional view of a stufting-box, showing my improved packing placed therein, and its form and the manner of arranging it in the box and around a pistonrod. Fig. 2 isa plan view ot' the packing 5o shown in Fig. l, cutaway at one portion ofits surface. Fig. 3 is a perspective view of a piece ofthe packing, and shows the method of Winding the metal and iibrous covering around the tubular core. Fig. 4 is a cross-section of the tubular core ot' a packing-ring.

Referring to the drawings, A represents a stutng-box; B, the gland or follower thereof. O is a piston-rod or other rod or piece to be packed, and D E F G H are five (more or less) packing-rings iitted around the rod C within the stufiing-box. These packing-rings areconstructed as follows: Take a tube, a, of brass or other suitable metal whose shapeis preferably that shown in cross-section in Fig. 4. This tube is continuous and hollow from end to end, and may be iiexible, so that its ends can be brought together', as shown in Fig. 2. The edges ofthe metal of which this tube a is composed'overlap each other slightly, as shown in Fig. 4, thus permitting a slight expansion and contraction of the tube, according as there may be pressure upon it from either side. Around this tube a, as a core, I wind a metallic wire, b, using preferably a soft wire, the coils of the wire being laid closely together around the tube to its entire length from one end to the other, and then they may be wound back again, breaking the joints of the rst winding, as shown at b2, Fig. 3, and then again wound back, if desired, breaking the joints of the second winding, as shown at b3, Fig. 3. The coils of the wire are kept from slipping oft' from the tube a by a iiange or iianges d, which may be bent up on the tube at either end thereof', and which may also serve to clamp and hold the ends ot" the wire upon the said tube. When the winding with the wire b has been completed I wind over said wire around the tube a the asbestus or brous covering e, in a series of close successive coils, covering the Whole surface of the wire I) on the tube a. Instead ot asbestus as a covering, I can use hem p, cotton, or other suitable tibrous material, and the same may be applied in strips or in any suitable manner which will efte'ctually Vcover and protect the tube a and metallic covering b. When the tube a is ot' triangular shape, as already stated, its form is transmitted to the succes sive windings, b and e, and the whole ring, when iinished, is triangular in cross-section.

.lOO

, I now vhave a flexible hollow strip, which is of the form shown or of other analogous form, and which may be made of various lengths, according to the diameter of the ring desired. When a series of these rings is slipped over the joints of steam-pipes, or over rods or stems into the boXA-one on top of the other-so as to make a close t, as show-n in Fig. l, a metallic packing is formed, which is readily applied, and which adjusts itself to varying conditions, on account ofits great flexibility'. As the ends d of the packingnring are not fastened rigidly together, but only brought close when the packing. is used, the steam or water will penetrate between the two ends and enter the hollow portion of the tube ct, filling it and acting as a further packing, and assisting in the objects for which my packing is intended; but if the ends of the tube be fastened very closely together, steam or water can be admitted to the hollow ot' the tube through apertures specially provided for that purpose.

In use, the triangular rings alternate to present alternately their bases and their apeX to the surface to be packed, as shown in Fig. l.

I can also make these hollow packing-rings with tubular cores of any angular form desired, or with a round or oval tubular core, the shape of the tubular core and the packing not being to said tube, Vand outer ibrous covering, e, sub-- stantia-lly as herein shown and described.

' 2. A packing composed of inner tube, a, having end ange or anges, d, and of the metallic covering b and fibrous covering e, substantially as herein shown and described.

3. Thehollowpaokingfrings of substantially the construction described, arranged one above another around the surface to be packed.

4. The hollow packing-rings having fibrous covering and opening or openings in the inner tube to admit steam or water, substantially as specied.

5. In a packing-ring, the inner tube, a, made with overlapping edges, substantially as and for the purposes specified.

This specification ot' my invention signed this 7th day of April, 1882.
